System Components Description
The Security Escort System consists of five basic components: Transmitters, Receivers, Alert Units,
Transponders, and the Central Console.
Figure 1: System Block Diagram
The Transmitter is a miniature, hand-held radio Transmitter used to transmit either a distress or a test signal.
The Receivers are located throughout the protected area and detect the radio transmissions from Transmitters.
Alert Units are Siren/Strobe units activated in the event of an alarm. Transponders are devices that control
groups of Receivers and Alert Units, connected to them by wire. Each Transponder relays alarm and test signals
from its Receivers to the Central Console. In addition, the Transponder tests for device and wiring faults, and
transmits problem conditions to the Central Console. The Central Console consists of a computer (plus an
optional backup and up to 8 optional workstations) which receives alarm and trouble signals from the
Transponders, analyzes the signals, activates Strobes and Sirens on the Alert Units, and produces a display for
the Security Dispatcher. Each of these system elements is described more fully in the sections that follow.
